I took it into mtn, they said that they don't know how long it will take to give me a quote, nor can they give me a price range... So I'm not going to take the risk of them taking a couple weeks from me!

So I went to another cell shop, they don't have parts!

I think I'm going to do the deed and order the front housing! Wish me luck!

Looks like I'm not the only one having troubles with my Motorola Defy.
I finally went for option 2 and repaired it myself for 15$.
Additionally I spent another 15$ and did http://www.motoroladefy.eu in order to bring a bit of awareness about this phone's fragility.
My phones works great again and I still save 120$ compared to Motorola's 150$ offer
